I had a schoolmate who seemed very friendly ever. A single time I've seen him in anger looked like an end of the world.Despite that, I'm still not warming up to Peck as Spock. Both Nimoy and Quinto had an intensity to their performance, that's just lacking in Peck. Nimoy and Quinto at times felt almost dangerous should they ever loose their tight control. Peck seemed... too friendly? Right from the start?
Peck's Spock was very dangerous (and stubborn) when prevented others to stop Burnham's dying during hunt on RA. Absolutely "my" Spock!
